For the reasons James pointed out, it's not easily solvable for the
"find the best thing to do, quickly".

Ad hoc works well for very small groups (<6) -- and in that case you
want them all to be in the same channel... to be able to communicate!
:-) It's for the "under a tree" scenario, no access points around.

If there is a lot of interference, it means there are lots of APs.
Just make one AP available to the XOs ;-)
